An Accommodation nestled in a forest with beautiful moon views, where you can unwind and lose track of time in harmony with nature.

In a place where you can witness the most beautiful moon in Japan, we envisioned creating a hidden retreat, and that dream led us to the serene forest of Kurokawa Onsen. "Kurokawa Onsen Gokoro Tsukikouju" is a Property where you can enjoy moonlight bathing in an open-air Onsen, while gazing at the moon shining in the sky. On a vast 4,500-tsubo estate, there are only eight villas. Each Room is uniquely designed and decorated, filled with delightful surprises. With the sound of the wind through the forest and the chirping of birds as your background music, surround yourself with only what you love and what is delicious, and indulge in the comfort of letting time flow naturally. This is a Property that promises such luxurious moments for adults.

  • We stayed in the new building at Gekkouju Kurokawa. As it was a brand-new Room, the entire guest room felt special, and everything—the spaciousness, quiet atmosphere, Onsen, and sauna—was wonderfully luxurious. We were able to forget about everyday life and truly relax.In particular, being able to enjoy the Onsen and sauna whenever we wanted without leaving the Room was incredibly appealing. During our stay, it felt like we spent almost all our waking hours either in the Onsen or the sauna.Each dish was carefully prepared and enjoyable both visually and in taste. Being able to take our time over dinner in a calm setting also became a very fond memory.Gekkouju is an Accommodation where not only the building, Rooms, and Onsen are outstanding—the warmth of the staff is what leaves the strongest impression.There are many luxury Onsen Accommodations and luxury Hotels, but what truly makes you want to come back is not just the Facility—it’s also the thoughtful hospitality of those who welcome you.This stay once again offered Gekkouju’s signature tranquility and indulgence, along with warm hospitality. It was an extremely satisfying visit.We would love to return as a couple.

  • We stayed at this Accommodation and were satisfied with everything. The luxurious L-shaped bath that extends from the Room to the outside is exceptional. The food, in particular, is delicious! If I may make one request: when moving guests’ private cars, please do not change the air-conditioning settings. When I got back into my car, the temperature was set to LO with the fan on full blast and it was roaring. Thank you for your understanding.\nI look forward to visiting again.
